Hilton Heydenrych

Systematic comparison of the effectiveness of water treatment processes

Qualifications

BSc (Eng) Chem

MSc (Eng) Chem


Project Description

This project is based on the hypothesis that existing processes for treatment of wastewater streams are not necessarily the most effective, partly because both the range of contaminants and treatment methods is very broad. This project is focussed on testing this hypothesis by modelling (on a single simulation platform) a wide range of proven water treatment technologies, combining these into both existing and new processes, and performing multi-criteria evaluations and comparisons of these processes (also using the available tools on the simulation platform). From the findings of this analysis, it is expected that new heuristic principles for the design of water treatment processes will be derived. In addition, a framework will have been developed in which models of emerging technologies can be incorporated and evaluated.
